TIDA-01580: Pulseoximeter (Heart Rate + SpO2) sensor

Part Number: TIDA-01580
Other Parts Discussed in Thread: AFE4900, AFE4950, AFE49I30, AFE4960P

Hello,

We are a company that develop and manufacture Health care devices. Now we have a solution to monitor patients in elder nursing homes using a selfmade wrist band. We were working with MAX32664C in combination with MAX86141 from Maxim Integrated. 

We developed a custom board including all the AFE (photodiodes and leds) including the MAX32664C which has a builtin alogrithm capable of reading all this data and reporting a reliable value of both SpO2 and Heart Rate.

Our application basically wakes up the device every 30min, takes just one Spo2 and HR sample and send it wirelessly.

We cannot finish the sensor part because Maxim Integrated has a quite poor support quality and we faced some problems that they were not able to solve (basically not answering emails).

I want to know if you could be able to pick a good sensor for me. I took a look at TIDA-01580 but I don't need ECG. This is a wrist application and that would be nice to have the data directly. Do you have a sensor AFE + algorithm to process all this data? 

Do I have to do it manually in the MCU? If yes, is it hard? 

Thanks,

Toni

    Hello Toni,

    Thank you for reaching out to TI and giving opportunity to support.

    In TIDA-01580, we have used TI's AFE4900 and Osram sensor for SpO2 & heart rate measurement. You can use the same sensor.

    TI has latest AFE device AFE49I30, AFE4950 as well as AFE4960P which can be used instead of AFE4900.

    Regarding algorithm, TI does not provide any algorithms as those are typically our customer's expertise and IP. We provide raw data which can be used to further process.To get started, TIDA-01580 comes with a basic filtering software in LabView which can be explored further.

    Of course, you can use MCU (like TI's latest MSPM0 https://www.ti.com/product/MSPM0L1306 or any other BLE MCU) for processing but we don't have any algorithms to support.

    Hope this helps. thank you.

    Regards,
